function color_field_field_widget_element_validate

Implements #element_validate function.

If a palette is set for the Spectrum widget, there are no default values available until the field has been saved. However, values are needed when a field is marked as required, otherwise errors occur. Therefore, when rgb or opacity are empty, and field is required, set the default values to rgb = #000000 and opacity = 1.
